I searched Google for this and it lead me to this site (great site!).

I also searched here but the threads that were most fitting were back in 2011 so I wanted to start a new thread.

Background:
I recently moved in with my girlfriend and the only option she has for broadband is ATT DSL and the router she must use is not the best.

It is a Netgear model B90-755025-15

The wifi drops periodically, the internet drops periodically, needs to be reset frequently, etc.

We can't really do much about the frequent internet drops as there are no other broadband providers in her area and AT&T doesn't want to fix it.

However, I do want to fix the internal network stability as we frequently stream music and movies from our NAS to our XBMCs.

I have an ASUS rt-66r that I would like to setup to handle the internal wifi and DCHP and just use the AT&T Netgear B90-755025-15 only when we go out to the internet.

I've tried connecting the two modems by cat6 and turning off the wifi on the ATT modem, as well as DCHP and still using the IP of the ATT modem as the gateway but that doesn't work.

I really appreciate any help here. What can I do to make the ATT modem only used for the internet and everything internal stay on the ASUS?

Yes

For the ASUS in the WAN section you want to setup as a static IP just to make it easy.

So if you DSL Modem is 192.168.1.1

Set the Ip for the router to like 192.168.1.254 Then the Subnet is 255.255.255.0 Default Gateway is the ATT router at 192.168.1.1 and the DNS is 192.168.1.1 (Or you can add in your own DNS as well but the 192.168.1.1 is fine since it will use the DNS that ATT Gives the Netgear

Then on your Lan the router can be what ever 192.168.2.X Ip you want and then the ENTIRE LAN/WiFi will be using the ASUS for all DHCP and LAN functions and then just the ATT when using the internet.

I don't know anything about that router BUT you can just plug from the LAN on the Netgear to the WAN on the ASUS. Just make sure they are different subnet.

So if the ATT Router is like 192.168.1.X network make sure the ASUS is a 192.168.ANYTHING BUT 1.X network. If the ATT router is what you want to run on your internal network (I like 192.168.1.X) just make the ATT to like 192.168.some other number that you don't want to use.X and yous should be fine.

Also if you play on doing any Port Forwarding, and the netgear has a DMZ in the firewall set it to the IP of the ASUS Router so that you can control the Port Forwarding from there.

Thanks for the replies.

drtweak, that sounds easy enough.

So if the DSL modem is using 192.168.1.x and I setup the ASUS to use 192.168.2.x and be DHCP and assign 192.168.2.x addresses
these addresses will use the IP of the DSL modem as the gateway? And they will be able to access the internet even though they are on a different subnet?

Read the first post. He is having issues with the Netgear as far as network stability goes and not just the WiFi/Internet and always having to reset the Netgear and having issues.

Why would you then want to setup it up as an AP (a very Expensive AP) and not use it as a router and all his local LAN traffic will be a lot more stable and then just reset the netgear when the internet is having issues.

Had it been ONLY a WiFi issue I would have told him to take it back and get an AP only which will cost half as much.

If the main router is instable, whether it feeds WAN or LAN ports of the secondary router / AP does not matter. If I was in OP shoes, I would dump the main router, get ADSL modem only (I also have ATT and have my run thru s^%%$y combos), and use RT66.
